The Lowdown
Alright, Rusty here. Let's take a look at what's on the table for Kennebunk Beach over the next couple of weeks.
Truth be told, it's a bleak start. We're looking at a solid string of poor surf days right through the end of August and into the first few days of September. The swell is small, the wind is messy, and there's just nothing to get excited about. You're looking at a gap of nearly a week with no real surf to speak of.
The first real glimmer of hope shows up on the 5th of September. The swell bumps up to a knee-high 3 ft out of the east with a 9-second period, and the combined energy is a moderate 150. The real kicker is the wind: glassy to light offshore conditions on the morning of the 5th. That's clean. It's not going to be pumping, but it'll be surfable. The water temp is sitting at 67°, which is a touch warmer than normal for this time of year.
Then, a proper standout appears on the 7th of September. Monday morning is looking like the pick of the bunch. The swell size jumps to 5 ft out of the east-southeast, with a 6-second period and a combined energy of 193. With the wind going dead calm and glassy, it's going to be clean as a whistle. The big caveat here is that 5 ft is getting into the territory where beginners might find it a bit challenging, and the period is short, so the waves will be a bit lumpy and sectiony. It's a beach break, so the short period won't be a deal-breaker, but it's not going to be a long-lined point break. For the more experienced crew, that morning session on the 7th is the one to aim for.
The afternoon of the 10th of September also has some potential. You'll see a 4 ft swell from the south-southeast, with a 10-second period, giving a combined energy of 367. That's a solid amount of energy. The wind is a light cross-offshore, keeping things clean. It's a good option for the second week, but long-range, so take it with a pinch of salt.
Beyond that, there are a few other mornings with waist-high surf and clean conditions, like the 13th of September, but nothing that truly stands out. The rest of the time is a mix of onshore winds and junky waves. If you're not a patient surfer, this stretch might be better spent on other things.
Signing off, Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
